They deorbit every 5 years and burn up in the atmosphere they don’t make it to land (although i think i remember a a part of a very early version did and changes were made because it did, but that might have been something else)
There have been a couple launches where some solar radiation caused damage or a problem with the stage 2 and they all came down and burned up before they made their planned orbit. On occasion, there may be a faulty satellite that doesn’t reach its proper orbit after launch and instead comes down instead.
Short of an error during launches, it’s all planned.
Why would they fall out of orbit?

Hundreds have already fallen out of orbit this year alone.
I think it’s mostly because they’re told to.
